  Purpose

It exists a learning curve in using NBI with magnification to differentiating colorectal lesions.


Condition
Colorectal Lesion

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: The Learning Curve of NBI With Magnification in the Diagnosis of Colorectal Lesions

Further study details as provided by Shanghai Jiao Tong University School of Medicine:

Biospecimen Retention:   Samples Without DNA

if the lesion is neoplastic or sm deeper cancer, we just take biopsy.If the lesion is adenomatous or sm1-2 cancer,we do polypectomy, EMR or ESD to get the specimen.

Study Completion Date: April 2011
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Detailed Description:

It is very useful to use narrow-band imaging and Sano CP analysis in the differential diagnosis of colorectal lesions. The endoscopists who had never used NBI or no knowledge of NBI can have effective and stable diagnostic accuracy after using NBI with magnification to diagnose 15 target and non-target lesions respectively.
